INTKODUCIION 19 



muiitlis when seeds are stored in a moist, warm climate; but where 

 the storage is dry, normal temperature ranges are not so important. 



L. The majority of carefully dried seeds can stand long exposure 

 to a temperature of 98, but 102 to 104 for a similar time will kill 

 them. In a moist air 86 will soon cause injury. 



M. Seeds to be sent to a moist climate should be shipped in air- 

 tight packages, but they must be dry before being sealed. 



N. Seeds under ordinary storage conditions respire most freely 

 when moisture is present, but respiration is not necessary to their 

 life, because they may be successfully kept even better for a time 

 under conditions unfavorable to respiration.
